Why do we floss for 2 minutes?

C Me C.
I asked my dentist this question. She advised that it’s not the amount of time we spend that is key, rather, it’s how well we focus on each tooth. Two minutes is a general guideline to ensure we spend enough time flossing instead of doing a quick in and out job. Sometimes it takes longer, sometimes we can do a through job in less time! What’s important is that we are thorough.
